Biden tweets condolences to Trump after brother's death

What they're saying: "Mr. President, Jill and I are sad to learn of your younger brother Robert’s passing. I know the tremendous pain of losing a loved one — and I know how important family is in moments like these. I hope you know that our prayers are with you all," Biden wrote in a tweet.

• Biden's running mate Kamala Harris added: "Doug and I join the Biden family in sending our deepest condolences and prayers to the entire Trump family during this difficult time. Losing a loved one is never easy but know that we are thinking of you."

Worth your time: In June, the New York Times, which described Biden as an "emissary of grief," reviewed nearly 60 eulogies that he had given throughout his career, offering "an intimate window into how he sought to comfort those joining him in mourning, and how he would seek to lead a nation grappling with death and devastation."
